Needs AT LEAST twice what you have for initial. Must have looked at a service manual for that 8* reading. Throw all the out because even back then, they didn't run well with the recommended idle timing. Turn it to 16 and reset the idle speed. I'll bet it's snappier!

You then need to recurve the distributor, it has WAY TOO MUCH mechanical advance in it.

33 Total is kind of light for total on an open chambered SB.
